LMDE 2 Cinnamon taskbar corruption

Post by takakia » Thu Apr 23, 2015 3:51 am

I have LMDE 2 Cinnamon 64-bit edition. After install everything goes well but there is a serious bug that if I open 10 windows or more at a time, the task bar collapses and becomes grey with no fonts on it. Even if I close the windows, it does not return back. I did not have this issue with LMDE 1. Does anyone have this problem? Please check the screenshot to understand the issue.

I just tried reproducing this on my desktop, it did not happen here. What graphics card are you using?

I had a similar problem using Intel graphics. For me though everything turned transparent rather than black like in your screenshot. Maybe the difference was the theme I was using? I was not able to find a solution and ended up using a different graphics card. I spent 3 days trying to solve the problem...

Corrupted graphics with Intel i915 driver in LMDE 2

Post by atarax » Thu Apr 23, 2015 3:59 pm

I just installed LMDE 2 Betsy on my netbook and since then the interface is corrupted in some areas. The Mint menu has a black background and in Firefox and Thunderbird the icons of various buttons just disappear when hovering them with the mouse pointer (see screenshot). In Chromium whole areas of the screen are blackened out and reappear when selecting page elements. In the release notes of Betsy a similar issue is mentioned, but I am not sure if this is the same bug that I experience. The recommended solution of 'killall caja' does not work in my case. On my desktop PC I have installed the same system without experiencing this bug. So it might be related to the graphics adapter. On the netbook where the issue happens I have an Intel 945 Graphic Media Accelerator working. Does anyone have an idea about this? Thank you.

PS: I am using the i915 driver from the xserver-xorg-video-intel package in version 2.21.15-2.

Exact same problem here:

Code: Select all

~ $ inxi -Gx
Graphics:  Card: Intel Core Processor Integrated Graphics Controller
           bus-ID: 00:02.0
           Display Server: X.Org 1.16.4 drivers: intel (unloaded: fbdev,vesa)
           Resolution: 1366x768@60.17hz, 1920x1080@60.00hz
           GLX Renderer: Mesa DRI Intel Ironlake Mobile
           GLX Version: 2.1 Mesa 10.3.2 Direct Rendering: Yes
This did not happen in LMDE 1:

Description:
- Affects only taskbar, start menu, Alt-Tab switcher and fonts in "Scale windows view"
- About transparency: really depends on the theme - and random effect - sometimes it turns transparent here, too
- Restarting Cinnamon sometimes resolves the problem, often not.
- Occurence randomly every few minutes
- Changes to Theme or font (Antialiasing and Hinting) resolve this temporarily
- Happens when many windows are open, but I am quite sure observing this with less windows open as well.

Very annoying. Love cinnamon but maybe have to switch to mate if there is no fix

This is different than the problem I had. For me the start menu and panel were not affected, menus in applications and newly started applications were completely transparent. If I knew where to click the mouse I could close out effected applications but ultimately I had to log off and back on to get things working again.

I could run for a couple of hours before seeing the problem, usually. In my case it was Intel G31 graphics using 8 MB shared memory. I installed an NVidea GT 220 that was setting in a drawer and have not had any problems since. Obviously this is not an option for everyone... What bugged me about the Intel graphics was that it could run Cinnamon just fine, the system never ran in software mode so it should have been capable of running.

When the system was using the Intel graphics it ran just as good as it does with the NVidea graphics, until the problem would appear. Have you updated the kernel? I tried with the default and upgraded kernel with no difference. Might be worth a try though?

kernel version is

Code: Select all

uname -a
Linux mcg 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt7-1 (2015-03-01) x86_64 GNU/Linux
I am reading about kernel updates now (latest stable 3.19 on kernel.org) but am not sure if this is a a good idea as I don't really know what could go wrong...

What I still needed to add that this is a fresh LMDE 2 installation and the bug happened right from the start with default settings.

I had the Intel problem with the stock install too. When I mentioned the kernel upgrade I meant the newer 3.16 kernel that comes up as a level 5 update in the package manager from Debian. I would not go with any other kernels that have not been tested. I tried the 3.19 kernel briefly, it made my hard drive make a lot of noise loading the desktop, I quickly removed it!

Another community member had problems with artifacts with Intel graphics in LMDE 2 Cinnamon. The same user did a Debian Jesse install with Cinnamon and the problem was not present. So there are 3 of us at least that have had problems with Intel graphics... The things he tried are posted as well as the things I tried, you might look over these and see if any of these ideas help with you situation.

The odd thing here is that all of us had somewhat different issues, the thing we all have in common is that we all used Intel graphics. I have searched the Debian forum for an answer but the problem is not presenting itself in Jesse as far as I can see. I looked through my log files and found nothing out of the ordinary that might provide clues as to what the problem might be related to.

Edit: Just checked and we are using the same kernel.

It appears that you are running LMDE 2 Mate. There are other threads on this issue but they are related to the Cinnamon version of LMDE 2. At least now we know that the issue is not specific to anything with Cinnamon. So far Intel graphics are the common factor... At present none of us have found a solution for this.

It appears the Mate version of LMDE is also affected. Now we know that this is not specific to Cinnamon.

Just an update:

Code: Select all

sudo apt-get upgrade ....
uname -a
Linux mcg 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-2 (2015-04-13) x86_64 GNU/Linux
Now "SMP Debian 3.16.7-ckt9-2 (2015-04-13)" but that does not solve the problem of course...

Update:
- Bug appears using one or two screens!

At least some good news - I like Cinnamon and did not want to switch to MATE - Change is off the table...

Just out of curiosity, are you running Firefox when the problem shows up or does it happen regardless running other applications?

I think I always have that open when the bug occurs, but not sure if a 100 % of the times - I keep an eye on that...

Thanks! I asked because there was a known bug in Firefox 37.0 relating to issues with certain graphics cards. Firefox has not been updated in LMDE 2 and I am wondering if this could be related? I could be wrong but it is worth looking into.

Sure.

Edit: The one marked solved is only because I changed graphics cards, the original problem is not solved. I had thought that the Intel graphics might not have been powerful enough to run Cinnamon but I was wrong about that... Since the issue has shown up on the Mate edition as well it seems the graphics capabilities were not the issue.

Edit 2: Changed the status of the above mentioned thread. :)

Tested uninstalling Firefox. Then opened 20 programs and it also crashed - apparently not connected to Firefox...

Again: the fix that always works temporarily is to change either
- theme
- font hinting
- font antialiasing

I tried different themes, same results as you had. Guess we can rule out Firefox too then.
